FLUSHlNG-VALVE.

SPECIFICATION forming part of Letters Patent No. 750,763, dated January26, 1904.

Application filed January 29, 1903.

To all whom it may concern:

Be it known that I, ROBERTF. GILLIN, a citizen of the United States,residing in the city of New York, borough of Brooklyn,in the county ofKings and State of New York, have invented a certain new and usefulImprovement in Flushing-Valves, of which the following is aspecification.

The invention relates to valves for controlling the flow offlushing-water to urinals; and the object of the invention is to providea valve which shall be simply and cheaply constructed, easily attachedto the urinal-bowl, and which shall be efficient and economical inoperation.

The invention consists in certain details of construction and novelarrangements of parts by which the above objects are attained, to behereinafter described.

The accompanying drawings form a part of this specification and show theinvention as I have carried it out.

Figure 1 is a face view of the upper portion of a urinal-bowl equippedwith my invention; and Fig. 2 is a corresponding side view, partly inelevation. The remaining figures are on a larger scale. Fig. 3 is avertical section through the valve and a portion of the urinalbowl, theplane of section being indicated by the line 3 3 in Fig. 1. Fig. 4: is aface view showing a modification; and Fig. 5 is a corresponding verticalsection, partly in side elevation.

Similar letters of reference indicate like parts in all the figures.

Referring to Figs. 1, 2, and 3, A is the urinalbowl, of earthenware, asusual, and of any approved type, having the nipple A, projecting fromits upper surface, adapted to receive and distribute the water admittedfor cleansing the bowl.

B is a shell, preferably a hollow cylindrical metal casting, having adownwardly-projecting bell B, adapted to loosely inclose the nipple Aand be firmly joined thereto by cement. The shell B has an opening ateach end of less diameter than the interior and is provided at one endwith a flange B adapted to apply against the wall.

Mounted concentrically in the bell is a tube Serial No. 140,986. (Nomodel.)

13, matching within the nipple and aiding to increase the strength ofthe connection and also to prevent the entrance of cement into thepassage through the nipple.

C is the body of the valve-casing, of less diameter than the interior ofthe shell and extending axially threrethrough, the outer end bearing aflange C and the inner end screwthreaded to receive a flanged thimble D,having acscrew-threaded extension D adapted to join the service-pipe M,bringing water under pressure from the street main or other source. (Notshown.) The joint between the casing and the shell, at each end. of thelatter, is made water-tight by gaskets E E, the former lying between theflange C and outer face of the shell and the latter between the innerface and the flange D on the thimble D and compressed by screwing thethimble upon the casing until sufficiently tight contact is insured.

Within the casing, near the inner end, is a diaphragm C having a centralopening surrounded on the rear face by an annular valveseat C againstwhich on the pressure side lies a packed disk or valve F, fastened by ascrew F to the end of a valve-stem F, extending through the casingaxially thereof and having a cone F serving as a reinforce to receivethe screw F and also to gradually reduce the area of the opening throughthe valve-seat as the valve approaches the latter in the act of closing.

(1* is an extension of the casing beyond the flange C, screw-threadedinteriorly to receive a hollow screw-plug G, the interior of which issmoothly finished to serve as a cylinder or dash-pot for a cup-leatherpiston F on the valve-stem F, the function of which is to compel thevalve to approach its seat slowly under the influence of thewater-pressure behind the valve and the expansive force of the helicalspring H, inclosing the stem and abutting against the piston F at oneend and the diaphragm C at the other. The outer end of the plug G isrecessed to form a stuffing-box G closed by a gland G through which theend of the stem passes.

The valve is operated by pressure applied to the head or button F on theprotruding end of the valve-stem with sufiicient force to overcome theresistance of the spring H and the water-pressure behind the valve. henthus thrust from its seat, water enters past the valve to the interiorof the casing and escapes through the opening 0 into the interior of theshell and thence through the tube B and nipple A to the bowl and isdistributed, as usual, to perform the flushing operation; As soon as thehand is removed from the head F the valve tends to reseat itself, but iscompelled to approach its seat slowly by reason of the dash-pot G, whichdetermines the period of closing. The cone F on the valve-stem bygradually reducing the eflective area of the valve-opening serves toprevent hammering or chattering of the valve on its seat in the act ofclosing. The opening 0 is shown in Fig. 3 as delivering the water upwardagainst the interior of the shell; but the opening may be otherwiselocated, as design or chance may determine, the position of the openingrelatively to the passage to the bowl being unimportant excepting as itpermits the flow to the bowl to be more or less direct, and thus offersa means of regulating the velocity of the flow through the nipple A. Ifthe water-pressure be high, the velocity will be lessened by locatingthe opening as shown in Fig. 3 and compelling the water escapingtherefrom to reverse its direction in entering the nipple, or, if thepressure be low, it may be permitted to flow directly from a low pointand he therefore less retarded.

In the modification shown in Figs. 4 and 5 the shell is formed in onewith the bowl by producing in place of the nipple A a hollow lug Ahaving oppositely-located openings in which the casing C is received andheld by gaskets E E lying between the flanges C and D and the front andrear faces of the lug. This form of the invention is preferable, for thereason that the separate casting or shell is dispensed with and also onaccount of the improved appearance of the bowll The form shown in theearlier figures is adapted to serve with bowls of the usualconstruction, while the modified form requires a speciallymade bowl; butit will be noted that the valvecasing and its operating means areentirely independent of the shell and may be used without change witheither form.

The disposition of the parts comprising the valve and its closing meanswithin the casing permits a very compact structure easily applied, andby means of the soft-rubber gaskets the joints between the shell andcasing may be made proof against leakage without danger of fracturingthe-fragile material of the bowl.

The thrust in opening the valve is directly in line with the attachmentto the water-service pipe, which, if properly secured, will aid inreceiving the strains, and thus relieve the earthenware and reduce thedanger of fracture.

It will also be observed that by arranging the valve to open against thewater-pressure the interior of the casing is relieved from such pressurewhen the valve is closed, and if the orifice c be at a low point all thewater in the casing may escape to the bowl, thus avoiding "submergenceof the spring and other internal parts, and consequently lesseningdeterioration by corrosion and increasing the life of the partsinclosed. To insure such drainage, I prefer to provide a series of smallholes 0, arranged annularly of the casing on the line of the orifice 0.Thus conditioned one or more of the holes 0 will always lie in thelowest portion of the casing and permit the slowescape of water withoutmaterially affecting the main discharge through the orifice 0.

I claim 1. A valve-casing having a water-inlet at one end and avalve-operating means at the other end, a valve within said casing, athimble on said inlet end having a flange, and a flange on the oppositeend of said casing, in combination with a shell receiving said casingand holding the latter by the engagement of said flanges with said shelland having a downwardly-projecting bell and tube extending within thesame, and a discharge-opening in said casing within said shell.
